What are some interesting plot ideas for Fairy Tail Dragon Cry fanfiction?

One idea could be that in a post - Dragon Cry adventure, Natsu and Lucy are sent on a mission to a hidden island where ancient dragon magic is said to be sealed. Along the way, they face various obstacles that test their bond, like a powerful sorcerer who tries to split them up. Another plot could involve Natsu losing his dragon slayer powers temporarily, and Lucy having to protect him while they search for a way to restore his powers using the knowledge from the Dragon Cry incident.

A possible plot is a magical artifact from Fairy Tail's world that is sought after by demons in Devil May Cry's universe. The Fairy Tail gang teams up with the Devil May Cry crew to protect it. The artifact might have the power to either destroy all magic or enhance it to uncontrollable levels. Dante and Natsu could have a friendly rivalry over who is stronger and who gets to fight the main villain. Another plot idea is that some of the Devil May Cry characters are sent back in time to the Fairy Tail world's past. They have to adapt to the magic - based society and help the Fairy Tail founders with a great threat that was once thought to be long forgotten.

Maybe the fanfiction could focus on a dragon slayer who loses their powers but then discovers a new way to regain them. For example, they might have to go on a spiritual journey and face their inner demons. Along the way, they form new bonds with the members of Fairy Tail, which helps them in their quest.

One common plot idea is a crossover where characters from Fairy Tail and Dragon Ball Super meet. For example, Natsu from Fairy Tail could team up with Goku from Dragon Ball Super to fight a powerful villain that threatens both their universes.

One idea could be exploring the origin of the Eye of the Black Dragon. Maybe it was created by an ancient magic long forgotten. Another could be a story where a character has to protect the Eye from dark forces who want to use its power for evil.

A simple yet interesting plot could be a race. The White Dragon could be part of a race in the Fairy Tail world, and some Naruto characters get invited. Naruto, with his speed and determination, could compete against the White Dragon and other Fairy Tail mages. It would be a test of different powers and abilities.

A really interesting plot would be if the world of the fanfiction was facing a threat that only the fire dragon powers could stop. But the catch is that the current fire dragon slayers have to combine their powers in a way they've never done before. They would have to overcome their differences and learn to work together, all while dealing with the increasing danger to their world.

A plot could involve Wendy using her Dragon Force to protect the Fairy Tail guild from a powerful dark magic user. She has to learn to control and enhance her Dragon Force abilities during the battle to save her friends. This could include her having to face her own fears and doubts about her power. For example, she might initially be afraid that she's not strong enough, but as the battle progresses, she realizes the true potential of her Dragon Force and how it's not just about raw power, but also about her connection to the dragons and her friends at Fairy Tail. In the end, she could defeat the dark magic user and become more confident in her abilities.

One idea could be an OC dragon slayer who has the power of a rare and ancient dragon. Their magic could have unique side - effects or abilities that no one has seen before. For example, instead of just breathing fire like a typical fire dragon slayer, they could create a special type of fire that can heal as well as destroy.

One idea could be to explore the backstories of the dragons more in - depth. Maybe show how they came to be involved in the wars in the first place. For example, there could be an ancient prophecy that led to their conflict.
